How to install Caffe

Installing Caffe

Installing Caffe on OSX

I installed Caffe on 10.11.6 using Homebrew Python and OSX Accelerate (was vecLib). Consider Anaconda and OpenBLAS for future installs, but I wanted to keep it simple (I could have used system python as well, but Caffe recommends hombrew as a second choice to Anaconda).

I installed python, numpy, scipy with Homebrew. Note that they are linked against Accelerate by default, so if using OpenBLAS these should be installed accordingly throughout the entire stack (and I think scikit-learn, which may be optional, should be installed after to properly link).

I followed the Caffe instructions for installation including the OSX specific stuff. It boils down to this:

brew install -vd snappy leveldb gflags glog szip lmdb
brew tap homebrew/science
brew install hdf5 opencv
brew install --build-from-source --with-python -vd protobuf
brew install --build-from-source -vd boost boost-python

Note: It appears that protobuf builds with Python by default and some instructions don't build from source...

As expected I had to modify Makefile.config. I disabled CUDA, enabled Python, and set paths.

Now build it:

make all
make test
make runtest

Then I manually installed remaining Python dependencies from caffe/python/requirements.txt using pip and build the Python bindings:

make pycaffe

Make caffe module visible to Python:

export PYTHONPATH=/path/to/caffe/python/:$PYTHONPATH

You can also dump the build into the distribute directory, including the python stuff if you have built it:

make distribute

Notes

I saw somewhere that DYLD_FALLBACK_LIBRARY_PATH is ignored in newer OSX. I didn't set and it built fine.

Could not locate Accelerate (using atlas) until I manually added the path in Makefile.config. It seems that Caffe Makefile is broken somehow does not set BLASS_LIB properly in my case (I didn't verify but BLAS_INCLUDE seems ok and could suggest a fix).

My path looks like this:

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
